PAGH 307 O27 od PREFACE So much has been written popularly and in a scientifie way on trees that no book on the subject would be warranted unless it was designed to meet a decided need. At present there is no general work upon American trees which combines illustrations of the individual forms with keys for their identification based upon winter characters. The forester and lumberman, however, are more called upon to distinguish trees in winter when leaves and flowers are fallen than in summer. ‘Trees, as the most con- spicuous elements in the winter landscape, must also appeal to the student of out door life. The interest shown by classes of school teachers in the Summer School in identifying specimens of twigs collected the previous winter indicated that the winter study of trees can be taken up with enthusiasm by teachers in their schools. In our experience, the winter identification of trees has proven to students one of the most interesting subjects of their course. It is of decided value for its training in the power of accurate obser- vation. The work comes at a time when material for natural history study seems scanty and might therefore be used to bridge over the period between fall and spring which are unfortunately considered by many the only seasons when study of out door life is possible in the schools. A tree in winter is far from being the characterless object many believe. Freed from its covering of leaves, the skeleton of the tree is revealed and with the method of branching thus clearly discernible, the species may generally be more readily identified at a distance than in its summer garb. There are many forms, moreover, that are difficult to distinguish from suminer features alone but which in winter have twig, bud or other characters which make their separation comparatively easy. It is believed that the combination of keys, text, and illus- trations from photographs will furnish the assistance which the current texts fail to supply and render the identification of our common trees in winter a relatively simple task. The text with keys is an outgrowth of outlines that one of the authors has developed and used with various modifications for the last four years in his college classes in Botany and Forestry. Co TD 0 NEW ENGLAND TREES IN WINTER. The photographie illustrations are all originals, most of them by the other author. Although one of us is responsible for the text and for the selection of the material photographed and the other for the photographs, we have freely consulted and the bulletin is therefore to be considered a joint publication. The order of arrangement of the species in the text and the scientific names follow the-usage of the seventh edition of Gray’s Manual and the latter are in aecord with the rules laid down in the Vienna Congress. The figures and descriptions given are of trees for the most part growing wild in New England. A few rarer species which occur in New England only very locally or in isolated instances have been omitted from illustration. In their places, however, some of the more frequently cultivated trees, have been included because of their value for forestry planting in New England or beeause of their familiarity in city ornamental plant- ings. The varieties of cultivated forms are so numerous that it is obviously possible to take account of only the most common types. Their inclusion, it is believed, will add to the value of the publi- cation especially for its use in cities. The keys can be absolutely relied upon only for the species just mentioned from New England. New England, including as it does the meeting ground between the northern and southern floras, is extremely rich in the species of trees represented. The bulletin, therefore, especially in its descriptive text and illustrations should prove of service outside of the geographically restricted region described. The final keys to the genera and to the species as well as the descriptive text in galley were placed in the hands of the present s in Botany and Forestry. A student after finding year’s cla the species by the keys, read the twig characters in the galley and signed his name opposite the species if the description corres- ponded with the twigs supplied. All of the trees described and illustrated have thus been checked up hy students and some of them by as many as seventy different persons. In this way limitations to the use of certain of the characters employed as means of separating allied species have been discovered and the constancy of other characters has been confirmed in so far as the material available could allow. The greatest assistance rendered by the students, however, has heen in disclosing difficulties in the use of the keys, due to unfortunate choice of contrasted characters or of STORRS AGRICULTURAL EXPERIMENT STATION. 309 terms used in their description. The keys in conse- quence have been considerably modified before final paging. Many of the explanatory phrases which may appear to be unnecessary have been inserted at the demand of the students. Where possible the most obvious characters have been employed and though the keys in consequence have become somewhat more cumbersome it is hoped they will prove more usable. Errors and omissions have no doubt crept in despite the efforts to avoid them. We would be grateful for any additions or corrections that may be suggested in the descriptions or keys in view of a possible revision of the text. The photographs of the twigs and of the fruit of the deciduous trees are very nearly natural size. They have been slightly reduced in production but all of them to the same scale, except the fruits of the Catalpa, the Chestnut, and the Honey Locust as indicated under these species. Line drawings or touched- up photographs would no doubt show important details more clearly by emphasizing certain of the minute markings. Since, however, these details are often obscure, and moreover receive full recognition in the accompanying text, it has been thought that a truer idea of the twigs would be gained if they were left as they appeared in the photographs. Accordingly, they have not been “doctored” in preparation or reproduction. The leafy twigs of the cone-hearing evergreens have been more or less reduced as indicated under the descriptions of the genera in the key. All the twigs of a single genus, however, are on the saine scale. LITERATURE The following is a list of books which will be found useful to the student of New England trees. They have been freely consulted, as well as others not listed, and have been of value in determining the ranges and wood characteristics of the indi- vidual species, in confirmation of bark and habit characters, and to a less degree of the other winter features. The dimensions of the trees in the heading “Habit” and the information under the heading “Distribution” have been taken with little change from Dame & Brooks’ Handbook, except what is given in the subhead- ing “In Connecticut” which was obtained from the catalog of the flowering plants and ferns of Connecticut; Bulletin No. 14, 310 NEW ENGLAND TREES IN WINTER. Conn. Geol. and Nat. Hist. Survey, 1910. The characters under the heading “Wood” were taken chiefly from Sargent’s Manual. To obtain information in regard to the dimensions, the distribution and the wood characters of cultivated species, Bailey’s Cyclopedia of Horticulture and various European works have been freely consulted.

ALBERT FRANCIS BLAKESLEE. CHESTER DEACON JARVIS. Storrs, Conn., June, 1911. STORRS AGRICULTURAL EXPERIMENT STATION. 313 INTRODUCTION Before considering the individual trees in detail it seems de- sirable to give a general discussion of the different terms used as headings in the description of the species. NAME tree and this name is used throughout the book as the designation A common English name heads the description of each of a particular species. The same form may be known in. different localities by several entirely different common names. Thus the Tupelo in some places is called only Pepperidge, in others, Sour Gum or Black Gum. After consultation with the literature the name Tupelo was chosen as being somewhat more desirable for the whole of New England than the other names given in smaller type as synonyms. Often several common names may be in about equally frequent use. There is, however, only one scientific name at present sanctioned by botanical authorities and this is placed first, followed by the Latin synonyms in italics. HABIT—By the word habit, we denote the general appearance of a tree seen as a whole. A tree strictly speaking is generally considered as a woody growth having an undivided trunk at the base and rising to at least twice the height of a man. cosa en om aL ga eve cate coe hoa a estan ean oe cael fs CORN A Plum (Prunus) 4) Terminal bud present: “6426.24 oa inadioe ts aera kaa Ree AS HAE Re Buds woolly at least at tip; collateral buds generally present. .. iso) Reset etpinc a aig haf a sch Coen th Era Winans mate RN span Peach (Prunus Persica) p.512 Buds smooth; collateral buds generally absent................-04- 2 Secruralseilel al chanel ops Dees Wild Red Cherry (Prunus pennsylvanica) p.500 (See also other cherries 144.)
